According to Mr. Gray, these shakes offer the “ideal balance of nutrients” for men and women. Don’t you love vague pseudo-science catch phrases?

You do? Great, because here’s another one: “the shakes are designed to assist the brain in functioning in a more balanced and harmonious manner.”

Mr. Gray also claims these shakes get you to your ideal weight. If you need to lose, you will lose. If you need to gain weight, you will gain. I would love to see the randomized double-blind control trials that confirm this (because I’m so sure he conducted them.)

Despite having the exact same ingredients in different amounts, Mr. Gray claims the Mars shake produces more dopamine in the brain, while the Venus shake produces more serotonin.

Huh? Both shakes contain a protein powder. Protein-rich foods cause a surge of dopamine. So, how then, does the Venus shake differ?

If you’re looking to lose weight, Mr. Gray has you covered!

All you have to do is buy his shake powder (of course!) and have it as your breakfast and dinner.

For lunch, you can eat a salad “with as many raw vegetables and avocado as you wish” as well as some form of protein, all topped with olive oil and either lemon juice or vinegar.

Although Mr. Gray claims the “effortless weight loss” (15 pounds a week, he claims!) is due to the magic ingredients in his shake, it’s clear that the “magic” is simple caloric deprivation.

How can you NOT lose weight if your only solid meal of the day is a salad and your other two meals each consist of one scoop of powder and eight ounces of water?

Despite all the fantastic claims, the small print at the bottom of his website reads “John Gray’s Mars & Venus LLC does NOT guarantee weight loss.”

Hmmmm… interesting how he never mentions that in his breathless infomercials where he mentions how “life changing” his shakes have been!

Now we come to my favorite part — the head-scratching nutrition-related statements:

*The weight loss cleanse prohibits the intake of any dairy, yet the shakes — which are a significant part of the cleanse — contain whey protein!

Newsflash, Mr. Gray, whey protein is a dairy protein!

* Mr. Gray on Omega-3′s: “A couple of tablespoons of flaxseed [have as many Omega-3's] as a meal of salmon.”

It’s such a shame that there will be so many people that will fall for this quackery simply because of the name associated with this ‘diet.’ I can only hope these people will be smart enough to do some research. Somehow, I doubt it.
